...Severe Thunderstorms Expected This Afternoon through the Mid
Evening Hours Across Middle Tennessee...
...Isolated Tornadoes With A Strong Tornado or Two Also
Possible...
A strong storm system will move from the southern plains into and
across Middle Tennessee this afternoon. Ahead of this frontal
system, as southerly winds pull warm, moist, and unstable air
across the mid state as the late morning into the afternoon hours
progress, some isolated strong to severe thunderstorms will
be possible. Also, as this frontal system moves across the mid
state this afternoon, strong to severe thunderstorms will
develop along and just ahead of the frontal boundary. Main
concerns with any severe thunderstorms that do develop will be
damaging straight line winds along with large hail. Isolated
tornadoes will also be possible, with one or two of these
potentially being strong, across the mid state region.
Presently, it is expected that the time window for greatest
potential for severe thunderstorm development will be between
12 PM - 3 PM CDT for locations across northwest Middle Tennessee.
For central portions of Middle Tennessee, including much of the
Nashville Metro Area, the best development window will be between
1 PM -5 PM CDT, impacting the afternoon rush hour traffic. For
locations just to the east, the greatest potential for severe
thunderstorm development will be between 3 PM - 7 PM CDT. For
locations near and across the Cumberland Plateau Region, the time
window is expected to be between 5 PM - 9 PM CDT.
Severe weather safety plans need to be in place before hand so
safety actions can be taken quickly if needed. Please stay tuned
to NOAA Weather Radio, visit the National Weather Service
Nashville, TN website at weather.gov/nashville, and local media
for further details or updates on this developing severe weather
situation.

...Severe Thunderstorms Expected late this Afternoon and Evening
across the Plateau, parts of the Central and Southern Tennessee
Valley, and southwest North Carolina...
...Rain Changing to Snow Showers across the Higher Elevations
Tuesday Night through Wednesday Night...
A strong storm system will move across the Southern Appalachian
Region today with southerly winds pulling warm, moist and
unstable air into the Tennessee Valley. Severe thunderstorms will
develop over middle Tennessee and northern Alabama this afternoon
and then move into the Plateau, southeast and central sections of
the Tennessee Valley, and southwest North Carolina this evening.
The main threat being tornadoes, damaging winds, and hail.
There is a potential of isolated strong tornadoes across the
southern Plateau and southeast Tennessee.
Besides the potential of severe storms, the strong low-level
winds may produce a Mountain Wave High Wind event across the
Mountains and Adjacent Foothills this afternoon and evening.
Southerly winds of 15 to 30 mph with gusts to 40 mph possible.
A cold front will move across the Tennessee Valley and southern
Appalachians Tuesday with colder air spilling into the region. For
Tuesday Night through Wednesday Night, the colder air will move
into the southern Appalachians with the rain changing to snow
showers across the higher elevations, generally above 2500 feet.
Snow accumulations are possible across the higher elevations, such
as the Smoky Mountains and High Knob, Virginia.
Anyone planning on venturing out across the higher terrain, such
as hikers, should plan for wintry conditions with temperatures
dropping into the upper teens and middle 20s, windy conditions,
and snow packed and icy trails. Best to delay venturing out
across the mountainous areas of the southern Appalachians.
Please stay tuned to NOAA Weather Radio and other local media for
further details or updates.
